Building on a long history of success in the railway industry, NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President & CEO: Toshihiro Uchiyama) has developed new high reliability gearbox bearings integrating advanced technologies that further increase reliability over previous models.
This includes new bearings for large and small gears (pinion shafts, etc.) in rolling stock gearboxes. The bearings for small gear shafts deliver a completely new level in value through even higher reliability and reductions in specialized maintenance requirements. The bearings for large gear shafts offer even higher reliability and the standard lineup has been expanded to offer a greater range of sizes to meet diverse customer needs.
High reliability is indispensable for gearbox bearings, which are subjected to severe conditions with frequent shocks and vibrations. The new bearings feature a suite of NSK technologies that significantly enhance the ease of handling (small gear bearings only), extend maintenance intervals, and contribute to a reduction in total life cycle costs.
Major rail operators in over 20 countries worldwide trust NSK railway bearings with a proven record of quality and reliability built on over 100 years of expertise in bearings, materials, and tribology. NSK has been generating significant momentum in the railway industry, and is moving to double sales by fiscal 2026 (compared to fiscal 2018).
Development is driven by NSK Vision 2026: “We’re Setting the Future in Motion,” which represents the company’s determination to create new value in mobility contributing to the development of a more prosperous society and enhancing value for all stakeholders, from employees and their families to the end user.
